UNITED STATES' PATENT Orincno GEBHARD KOEB, OF SPRINGFIELD, OHIO, ASSIGNOR OF ONE-HALF TO JACOB B. 'KORN, OF SAME PLACE.

STOVEi-PIPE COLLAR.-

SPECIFICATION forming part of Letters Patent No. 374,974, dated December 20, 1887.

Application filed March 7, 1887. Serial No. 230,009.

To all whom t may concern:

Be it known that l, GERHARD Kenn, a citizen of the United States, residing at Spring field, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Stove-Pipe Thimbles, of which the following is a specification, reference being had therein to the accompanying drawlngs. l

This invention is an improvement in stovepipe thimbles; and it consists, essentially, in combining a metallic band or wire vwith the collar of the thimble, and in passing it round the collar and providing it with fastening devices, so as to draw its ends together,contract the collar, and cause it to bind the pipe and prevent it from projecting into the iiue too y far, which would obstruct the draft; and it also prevents it from coming out andrdropping down, which would be liable to cause iire. i

In the accompanying drawings, forming a part of this specification, and on which like reference-letters indicate corresponding parts, Figure l is a sectional view of the wall and of my improved thimble, as also a view of theV cap in elevation and removed; Fig. 2, a like view of the wall, showing the thimble and a section of pipe in side elevation; Fig. 3, a face view of the thimble, and Figfet a sec tional view of a modification in the manner of securing the collar to the ring portion of the thimble.

The letter A designates a chimney-wall or other wall of a building, having the usual pipehole, B, therein, and the letter'C the ring portion of the thi1nble,whicli fits snugly to the wall and prevents soot from accumulating between it and the'wall.

As usually made, the rings are curved in cross'section, the edge only touching the wall, while at the inner circumference thereof they stand away from it. This allows soot to gather and to work its way out and then fall upon the floor beneath.

The letter D refers to the collar, the saine being fitted to the ring, secured in any desired manner, and extended some little distance beyond it, so as to enter the pipehole in the wall and act to support the ring additionally to the nails or other fastenings, E, or to hold it entirely when such fastenings are not used. The collar, by preference, has its (No model.)

outer edge turned outwardly to form a fiange, F. f

The collar is also slotted at several points, as seen at G, so as to allow its diameter to be contracted by a band, H, which encireles it, and which has a fastening by which it is drawn tightly upon the collar. The fastening consists in bending the ends ofthe band H outward, and providing the ends with holes, and with a bolt and nut, I, or thumb-screw. rI`he flange F prevents the band H from slipping olt' the collar. When the band is drawn, the collar is contracted, as already suggested, and the stove-pipe is consequently clamped and firmly held. This connection also prevents the chimney and the room from communicating through the space so frequently existing between the pipe and thimble. The band may vary in shape in cross-section; but the Hat band is preferred.

In Fig. 4 I have shown the collar provided with an annular groove or depression, into which tits a corresponding head, J, extending inwardly from the ring C, the ring being also provided with a flange, K. The cap L (shown in side elevation iu Fig. I) serves to close the pipe-hole in the wall when the pipe is not in use; and'it consists of a sleeve, M, which fits within the collar D, and is held therein in the saine manner that the pipe is held therein--` namely, by the band II being contracted. At N the sleeve M is slotted, which permits of the sleeve being compressed, so as to more readily enter the collar, if such should be necessary. The letter O refers to the head of the cap.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a pipe-thinible, the combination, with the ring portion :fitted against the wall and a collar fitted thereto, having its outer edge turned outward to forni a fiange and slotted IOC
